The protest began Monday with 13 hunger strikers - seven of them in jail, six of them free, including Beatriz Roque.
More dissidents have since joined the demonstration, which now totals 26 hunger strikers, Diario de Cuba reported.
The hunger strikers are demanding the release of Jorge Vázquez Chaviano, a political prisoner who was supposed to be freed Sept. 9.
